MMIC Package Customization – Footprint-Compatible Solutions for Your System Obsolescence Management and EOL Part Replacement LTB (Last Time Buy) and EOL (End of Life) are among the most unwelcome acronyms in the ranks of Procurement and Engineering. Component obsolescence saddles customers with the burden of tying cash up in inventory on their balance sheet, or […]
MMIC Technologies: Pseudomorphic High Electron Mobility Transistor (pHEMT)
Pseudomorphic High-Electron-Mobility-Transistor (pHEMT) is one technology Monolithic Microwave Integrated Circuit (MMIC) designers and fabs use to develop and manufacture microwave integrated circuits. pHEMT has gained popularity as a building block of many MMICs produced by electronics manufacturers like Mini-Circuits due to its superior wideband performance characteristics including low noise figure, high OIP3 and excellent reliability up to 40 GHz and beyond. pHEMT uses heterojunctions between semiconductors of different compositions and bandgaps to achieve outstanding high-frequency performance. This article delves into the physics of pHEMT operation, advantage, and reliability test results. A link to a summary of Mini-Circuits’ pHEMT products is also provided.
Flattening Negative Gain Slope with MMIC Fixed Equalizers
Equalizers are devices used to compensate for negative gain slope in the frequency response of a wide variety of RF systems. Unlike a standard attenuator with a flat frequency response, an equalizer is a unique kind of attenuator which exhibits lower insertion loss as frequency increases with some known slope. This is a useful characteristic for system designers working in wideband applications where the gain response of circuit elements or of the entire RF chain often varies across frequency.
